“The defendant did intentionally damage her dwelling by pouring gasoline inside her residence which was later set on fire by a co-defendant, causing complete loss of the residence,” stated Kimberly Koster’s indictment.

It also claimed her daughter participated in the incident “by starting a fire when she intentionally lit a match and placed it on a pile of clothes inside the residence.”

The indictment did not elaborate on Dietzman’s alleged participation in the incident. He was arrested after the Kosters were initially charged with the crime.

A number of area fire departments responded to the 10:20 p.m., Aug. 13 fire at 1636 State Highway 235 after a neighbor called 911.

Firemen found the unoccupied home engulfed in flames when they arrived. Within a few hours, fire investigators inspecting the building’s debris found evidence of foul play and contacted the Chenango County Sheriff’s Office.
